Federal Signal G-SND-MV-D Sounder for Use in Hazardous Locations

Built to protect people and assets in the toughest environments, the Federal Signal G-SND-MV-D Sounder delivers dependable, explosion‑proof audible signaling for hazardous locations. This Global Series sounder is certified for gas Group IIC environments and offers both Ex (explosion-proof) and Ex de increased-safety wiring box options, so you can deploy it with confidence in combustible atmospheres. Installers benefit from AC/DC power support — including 240V AC input — and a compact, surface-mount form factor that eases retrofits and new builds. Operators gain flexibility with a rotary-selectable single tone or remote multi-tone inputs to distinguish alarm types or escalate conditions, improving response times for security, surveillance, and monitoring systems. Compatible with other Federal Signal Global Series audible and visual modules, the G-SND-MV-D supports integrated signaling strategies across industrial security and safety networks. For mission-critical facilities requiring robust, certified audible alarms, choose the G-SND-MV-D — contact us to configure a factory-custom assembly or order the optional coupling kit for field installation.
